1bpp 图像中的简单形状检测
我正在尝试了解我正在从事的项目的简单形状检测。
我有一个仅由黑白像素组成的图像，我需要检测图像中的形状，例如正方形和椭圆形。我还需要找到形状的边界框。
我一直在网上搜索并阅读文章，但我找不到任何关于从哪里开始的好的解释。
我也在寻找一些部分/完整的代码示例，最好是 Java 或 C++ 的。
谢谢！
I am trying to learn about simple shape detection for a project I'm working on.
I have an image that is made of only black and white pixels and I need to detect shapes within the image, such as squares and ellipses. I also need to find the bounding boxes of the shapes.
I have been searching online and reading articles but I can't find any good explanations of where to start.
I am also looking for some partial/complete code examples preferably in Java or C++.
Thanks!

进行边缘检测有几种不同的方法，其中一种称为
Canny 边缘检测。查看 此网站，该网站具有该算法的 Java 实现发布到公共领域。There's a few different ways of doing edge detection, one of the ways is called
Canny Edge Detection. Check out this website which has a Java implementation of the algorithm that has been released to the public domain.我不知道有哪个库或工具包可以使这种操作变得微不足道，但如果您真的想了解这种逻辑是如何工作的，请从这里开始
I'm not aware of a library or toolkit that makes this kind of operation trivial but if you really want to understand how this kind of logic works, start here http://opencv.willowgarage.com/wiki/
